Fc setup questions
Hello I am planning on getting a street ported s5 tii motor built by Atkins, already have greddy front mount, racing beat full 3" exhaust and an s4 turbo, manifold and ecu, I do plan on going with an aftermarket turbo and full stand alone however I want to get my car on the road sooner then I'll be able to afford that. My question is can I run rtek 2.0 on a street ported motor and stock turbo? I know the turbo will be pretty undersized for a street port but like I said I just want to get my car on the road and save up for the expensive goodies.
Also I know that I will have to adapt the s4 turbo wiring to work with the s5 motor.
Another question is can I run stock injectors with the rtek and street port or should I plan upgrading Injectors before the motor goes together? If so what size?
Thank you for any help!

Rtek 2.0 will be fine. You will want at least 1000cc fuel injectors, or you will run out of fuel...

For the best performance you should restore the functionality of the twin scroll system. It will work fine w/o it but you lose some low end. however, you said you have an S5 engine and n370 (s5 ecu) so twin scroll doesn't sound like an option for you. Why do you have an S4 turbo anyway?

Well, I picked up an s5 turbo swap. I'm planning on getting an Atkins s5 street ported block, (from what I've read it's better then s4 to my knowledge) was gonna get s4 turbo wiring harness afm and already have the s4 tii ecu. Swap came with a no good s5 turbo with cracked manifold. Found a what seems to be nice s4 turbo and mani locally for cheap so I figured run that for the time being. But I'm on here cuz I'm trying to learn this as I go from experienced people so please let me know if I'm going about this ackword bass.

Check out BNRsupercars.com for the differences between S4 and S5 turbos, mainly the S5 will flow more on the exhaust side, will spool just as good (but without the "quickspool" actuator) and the wastegate area is larger.
One problem I feel you will definitely encounter with a streetported block is that you will get boost creep with the S4 unit. The S5 has dual wastegate flappers, and once ported MAY be able to keep boost in check.

I have sort of a similar setup...
RTEK 2.0 on a kouki computer
Stock port kouki motor
kouki turbo
I have 720 ID primaries and 1000 ID secondaries with an aeromotive FPR and a warlbro pump. It's plenty of fuel for the setup.
I wasn't really happy with it until I added the aeromotive regulator. My OE FPR would heat up and give me fuel pressure problems.

No. Kouki = late model = S5
Boost creep is always bad, it means that your system is doing something other than what you intended and that you cannot control. It may not always cost you an engine but it is never desireable ( or even tolerable depending how uncompromising you are).
550/720 is enough fuel for anything the stock turbo can muster, anything larger is just safety margin, nothing wrong with going larger, just not a requirement.
As far as the wiring, just use all your s4 accessories with the s5 short block , that makes things very easy.

Surprisingly, I'm not having any luck finding links to see what all I can delete from my wiring harness with my set-up and running rtek 2.1 and again with haltech...
Also, just wanna make sure that on a streetported block and stock turbo I can run oem primaries and 1000cc secondaries?

The stock wiring and an Rtek: use the injector wires,coolant,oil,tps,coils,AFM,boost sensor,etc.
I got rid of the solenoid ****.The engine was just injectors and sensors.Of course the AFM was still in the mix.
When you go Haltech you keep only the driver's side harness.The old stock ECU engine harness is taken out and replaced with the haltech harness.This harness will attach to injectors and sensors,coils.No Afm is needed with the Haltech.
Not the best Info,but I hope you get the drift.
